Uhhh, switch statements run VERY FAST. Even faster than if statements. Switch is better here because there are a limited number of options that exist in easily ascending order. When it's like this, the assembly XORs a single digit and knows exactly where to JMP. An if-then structure would require, worst case, 20 CMPs. On top of that, switches are easier to maintain (though Nexon clearly doesn't take advantage of it).
In short, Switch statements when using a branch table run in O(1) time. If statements run in O(n) time.
